Description

Technical Field

[0001] The utility model relates to the technical field of automatic doors, in particular to an automatic door driving mechanism. Background Art

[0002] Automatic doors are systems that open the door through a drive system, automatically close the door after the person leaves, and control the opening and closing process. Common automatic doors include track-type sliding doors and folding sliding doors. Track-type sliding doors open and close the door by moving the door assembly on the track assembly. However, this type of track-type automatic door occupies a lot of space and is not convenient for installation and use in some occasions. The other type of automatic door is a folding sliding door, which is opened and closed by driving two or more door assemblies to fold and extend through a drive mechanism. It occupies a small area and is suitable for use in narrow door frames.

[0003] However, when the existing folding sliding door is in use, the two door components are generally connected by an ordinary hinged connection. This connection is not smooth enough during the folding and extending process, resulting in the door components easily making loud noises, getting stuck, or even being damaged during the folding and extending process.

[0004] Therefore, the present application provides an automatic door driving mechanism to solve the above technical problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an automatic door driving mechanism to solve the problem that the folding and stretching between the door components of the existing folding automatic door are not smooth enough to affect the use.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] An automatic door driving mechanism comprises a column, a first door leaf is hingedly mounted on one side of the column, a second door leaf is hingedly mounted on a side of the first door leaf away from the column, a first slider and a second slider are slidably mounted on the inner bottom of the first door leaf, a rotating connection block is fixed to an end of the inner bottom of the first door leaf away from the column, and a fixed block is fixed to an end of the inner bottom of the second door leaf facing the first door leaf;

[0008] A support seat is fixed at the bottom of the column, a connecting rod is movably installed on the support seat, the connecting rod is fixed to the first slider, a retractable cover is fixedly installed on the first slider and the second slider, a U-shaped link that can be wrapped along a corner of the bottom of the first door leaf is movably installed at one end of the second slider away from the retractable cover, and the U-shaped link is movably connected to the rotating connecting block and the fixed block at one end away from the second slider.

[0009] Optionally, two horizontal sliding bars are fixed to the inner bottom of the first door leaf, and the first sliding block and the second sliding block are respectively slidably mounted on the two sliding bars at the inner bottom of the first door leaf.

[0010] Optionally, the support seat, the connecting rod, the telescopic cover and the U-shaped link are all located on the same horizontal line.

[0011] Optionally, the retractable cover shell includes a main shell, a first connecting shell and a second connecting shell, and the first connecting shell and the second connecting shell are respectively plugged and installed at two ends of the main shell.

[0012] Optionally, a fixing groove is opened in the middle of the main shell body corresponding to the positions of the first connecting shell and the second connecting shell, and a plurality of fastening bolts are arranged in the fixing groove. The fastening bolts pass through the fixing groove and are threadedly fastened with the corresponding first connecting shell and the second connecting shell.

[0013] Optionally, the U-shaped link includes a first link portion, a second link portion and a third hinge portion, the first link portion is movably mounted on an end of the second slider away from the retractable cover, the second link portion is movably connected to an end of the first link portion away from the second slider, and the third hinge portion is movably connected to an end of the second link portion away from the first link portion.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, thanks to the setting of the retractable cover and the U-shaped link, the first door leaf and the second door leaf can be movably connected, so that when the second door leaf is pulled by a driving mechanism (such as an arm), it can use the U-shaped link to move around the bottom end of the first door leaf, and cooperate with the retractable cover to drive the first door leaf to fold in half relative to the second door leaf, thereby forming a fold and completing the extension. Therefore, the device can effectively ensure the smoothness of the folding and extension of the first door leaf and the second door leaf through the guidance of the support seat, connecting rod, retractable cover and U-shaped link, and is conducive to avoiding the door assembly from making loud abnormal noises, getting stuck and being damaged during the folding and extension process, and has a good use effect.

[0034] At the same time, a support seat 4 is fixed at the bottom of the column 1, and a connecting rod 5 is movably installed on the support seat 4. The connecting rod 5 is fixed to the first slider 201, and a retractable cover 6 is fixedly installed on the first slider 201 and the second slider 202. A U-shaped link 7 that can wrap along a corner of the bottom of the first door leaf 2 is movably installed at one end of the second slider 202 away from the retractable cover 6, and the end of the U-shaped link 7 away from the second slider 202 is movably connected to the rotating connection block 203 and the fixed block 301. In specific implementation, the support seat 4, the connecting rod 5, the retractable cover 6 and the U-shaped link 7 are all located on the same horizontal line.

[0035] like Figure 3 and Figure 4 As shown, the telescopic cover shell 6 includes a main shell 601, a first connecting shell 602 and a second connecting shell 603, the first connecting shell 602 and the second connecting shell 603 are respectively plugged and installed on the two ends of the main shell 601, and a fixing groove 604 is opened in the middle of the main shell 601 corresponding to the position of the first connecting shell 602 and the second connecting shell 603, and a plurality of fastening bolts 605 are arranged in the fixing groove 604, and the fastening bolts 605 pass through the fixing groove 604 and are threadedly fastened with the corresponding first connecting shell 602 and the second connecting shell 603.

[0036] Cooperate Figure 5 As shown, one end of the first connecting shell 602 extending out of the main shell 601 is fixed to the first slider 201, and one end of the second connecting shell 603 extending out of the main shell 601 is fixed to the second slider 202, so that the retractable cover shell 6 is installed on the first slider 201 and the second slider 202 to form a connection.

[0037] During specific implementation, the length of the telescopic cover 6 can be flexibly adjusted according to actual installation requirements, which is more convenient to use.
